Hi, Let’s delve into microbiology and learn about gene transfer mechanisms: Transformation, Transduction and Conjugation. http://pathmicro.med.sc.edu/mayer/genetic%20ex.htm Some good information with pictures can be found HERE.
Mendelian and Population Genetics
Hi, Below you will find practice questions for genetics. At the end you will find the answers. www.pypop.org/thomsonlab/files/MCB142practice5-12.pdf
Biology olympiad papers in German or French
Hello, I found some good past papers of biology olympiads in German or/and French language. Take a look HERE, HERE and HERE.
ELISA: Enzyme Linked Immunosorbent Assay
Hello, Today you will learn about ELISA – Enzyme Linked Immunosorbent Assay. The enzyme-linked immunosorbent assay (ELISA) is a test that uses antibodies and color change to identify a substance. Here and here you can find interactive ELISA tutorials. Here is another good interactive presentation. http://en.wikipedia.org/wiki/ELISA https://www.sdstate.edu/sdces/fcs/upload/ELISA_Part1_PPT.pdf
Transfection and Infection of Mammalian Cells
Hi dear, In this post you will find information about transfection and infection of mammalian cells. http://web.mnstate.edu/provost/ Biotech vector created by freepik – www.freepik.com
Gene Transfer in Plants
Hi, In this tutorial you will learn about various methods used in gene transfer in plant cells. http://web.mnstate.edu/provost/
Cell Counting
Hello, In this lesson you will learn how to use a hemocytometer and how to count cells in your culture. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm. Firstly, take a look at a video so that you understand what it is all about. To end with, another good video.
Plant cell cultures
Hi, In the previous post we discussed animal cell cultures and we now proceed to plant cell cultures which have some specific attributes to remember. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm Take a look at the video about aseptic technique while working with plant tissues.
Animal cell cultures
Hello, After some break, we will continue delving into biology. In this lesson you will find out about animal cell cultures. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm. Before we begin, take a look at this video which presents how everything looks in laboratory. To end with, one more video: Human cell vector created by brgfx – www.freepik.com

Population genetics III
Population Genetics is the study of genetic events at the level of the population. Below is a handout which will help you understand population genetics better. http://www.bio.miami.edu/dana/250/25009_16print.html.
Electron transport system
Embedded in the inner membrane of the mitochondrion are a bunch of protein complexes that are involved in electron transport. They make up the electron transport chain (ETC). HERE you will find an amazing website VIRTUAL CELL ANIMATION COLLECTION. Take a look at an electron transport chain (ETC). HERE there is another good video about ETC in mitochondria. Useful animations …
Amino Acids & Proteins
For the hardest part in biology olympiads has always been biochemistry. Thus, I would like you to be the best in this field, so here you will find some good notes of amino acids and proteins from the biochemical point of view.Especially pay your attention to isoelectric point and pK calculations. The isoelectric point, sometimes abbreviated to IEP, is the …
